silver arowana

Silver arowanas are elongated fish with large, pearly silver scales that can shimmer with hints of red, blue, and green as the fish ages. They have a distinctive, upturned mouth with two barbels (sensory whiskers) on the lower jaw and large, armor-like scales that have led to their nickname “dragon fish”.
They can grow to an impressive size, typically reaching 3 feet in length, with some individuals reported to reach nearly 4 feet.

Habitat: In the wild, silver arowanas inhabit the floodplains of the Amazon River, including both blackwater and whitewater environments. They prefer slow-moving or still waters like tributaries, backwaters, and lagoons.

Diet: Silver arowanas are carnivorous predators that primarily feed on fish at the surface, but will also consume insects, crustaceans, and even small frogs and other aquatic animals.
In captivity, a balanced diet consists of high-quality pellets or sticks designed for carnivorous fish, supplemented with live, frozen, or freeze-dried foods like fish, insects, krill, and shrimp. Juveniles should be fed 2-3 times daily, while adults can thrive on a single daily feeding.

Behavior and temperament: These fish are active hunters and are known for their jumping ability, which they use in the wild to catch insects and other prey from overhanging branches. They can be surprisingly skittish, reacting to sudden movements or changes in their environment, according to Aquarium Source.

While generally less aggressive than some other arowana species, they are predatory and will attempt to eat any fish that can fit into their mouth, says YouTube.
Adult arowanas are generally solitary and keeping more than one in the same tank can lead to stress, aggression, and competition.

Reproduction: Silver arowanas are mouthbrooders, with the male carrying the fertilized eggs and caring for the fry in his mouth until they are able to feed themselves.
